I get similar results shooting from a bench with kodiak or barracuda 31.02. When hunting its always from bipod or 4' shooting sticks which opens the group up another 1" or more depending on the conditions on a given day. Also, I never change my scope off of 10x mag because thats where I learned my holdovers and it changes with scope mag changes. I dont have any issues shooting at that magnification so why change now?
